EDWARD EBI, OF CEDAR RAPIDS, IOWA.

BRAKE-R0 D.

SPECIFICATION forming part of Letters Patent No. 246,101, dated August 23, 1881.

Application filed March 30, 1881. (Model.)

To all whom it may concern:

Be it known that I, EDWARD EBI, of Cedar Rapids, in the county of Linn and State of Iowa, have invented anew-and Improved Brake-Rod, of which the following is a specification.

The object of my invention is to facilitate operating all the brakes of a train simultaneously from the locomotive. Y

The invention consists in a rod passing through journal-bearings on the under side of the car, and provided at the ends with pivoted connecting bars having spring catches for keeping them united, which connectingbars are locked to the brake-rods by means of a lever pivoted to the connecting-bar and passing into notches of a loose and a rigid circular plate on the brake-rod, so that all the brakerods of the several cars of a train will be revolved together and the brake-shoes will be drawn against the wheels simultaneously.

In the accompanying drawings, Figure l is a side elevation of two connected ends of my improved brake-rod. Fig. 2 is a plan view of the same. Fig. 3 is a cross-sectional elevation of the same on the line x 00, Fig. 1. Fig. 4 is a cross-sectional elevation of one of the connecting-bars with its clamp and spring-catch.

Similar letters of reference indicate corresponding parts.

The rods A A pass through journal-bearings B B, suspended from or attached to the under side of the car, so that these rods can be rotated freely. A circular plate, 0, with a notch, D, and provided with jaws E, is loosely mounted on the end of the rod A, and a bar, F, is pivoted to the jaws E. A circular plate, G, with a series of notches, H, in the circumference, is rigidly mounted on the bar A, adjoining the plate (J; and if a latch-lever, J, pivoted on the bar F, is passed into the notch D of the plate 0 and into one of the notches H of the plate G, the two plates G and C will be locked to each other. A spring, K, holds the latch-lever J in its various positions. A U- shaped clamp, L, is attached to each bar F in such a manner that this bar rests against one of the shanks and against the transverse piece M of the clamp L, as shown in Fig. 3.

A spring-latch, N, with an outwardly-beveled end, is attached to that shank of the clamp L against which the bar F rests, so that this latch passes across the clamp, and its pomtis adjoining the other shank.

The brake-chain I is attached to the bar A, and will be wound upon the same when the bar is rotated by suitable mechanism.

The operation is as follows: Ordinarily the connecting-bars F hang down from the ends of the bar A; but when two cars have been coupled one bar F is passed into the U-shaped clamp L of the other, and is retained in the same by the spring-latch N, this bar F pressin g the spring of the latch N inward as it en- I ters into the clamps L. If the cars are uncoupled, the bars F simply slide out of each others clamps, and then hang from the end. of the rods.

The rods A of all the cars of atrain can be connected in the manner described above. If the latch-lever J is raised, the connecting-bars F will not be rotated, and thus any number of cars can be disconnected, if desired.

The red A of the locomotive is rotated by means of some suitable mechanism on the 10- comotive, and the movement of this bar A is transmitted to the others in the manner shown and described.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the rod A, journaled on the under side of a car, of the notched circular plate (3, the pivoted connecting-bar F, the notched circular plate Gr, and the latchlever, J, pivoted to the connecting-bar F, substantially as herein shown and described, and for the purpose set forth.

2. The combination, with the rod A, journaled on the under side of a car, of the connecting-rod F, pivoted to a notched circular plate, 0, loosely mounted on the end of the rod A, of the notched circular plate G, rigidly mounted on the rod A, and of a U-shaped clamp, L, attached to the connecting-rod F and provided with a spring-latch, N, substantially as herein shown and described, and for the purpose set forth.

3. In a brake-rod connection, the connecting-bar F, constructed substantially as herein shown and described, with an U-shaped clamp, L, provided with a spring-latch, N, attached thereto, as and for the purpose set forth.

EDWARD EBI.
